The present invention is related to the cold start current CCA specification of the starter battery, and particularly refers to a lower performance starter battery and fast energy storage module parallel output ratio configuration system and lower performance starter battery and fast energy storage module parallel output ratio Configuration method.

Current devices that use starter batteries (such as lead-acid batteries) to start the engine, due to the need to instantaneously draw a large current, multiple operations will cause the starter battery to deteriorate, resulting in an increase in internal resistance, but the large current drawn when starting the engine remains unchanged Under the circumstances, the start-up battery accelerates to deteriorate, causing the start-up battery to gradually fail. The start-up battery, such as a lead-acid battery or others, will affect its life due to different pumping currents.

The load current of the starter motor of the existing automobile and locomotive is very large. Taking a 3000C.C. car as an example, the starter motor may reach 500 A ~ 600A with a pumping load. In order to meet this pumping current, a larger-capacity starter battery is often required. If a 55 Ahr starter battery is selected, the starter battery still uses 10C current to discharge, so it is still easy to reduce the battery life after multiple charging and discharging. This phenomenon has led to the fact that the volume capacity and weight of the current starting battery of automobile and locomotive are quite large and the life is also quite short; therefore, how to reduce the volume capacity and weight of the battery but still start the automobile and locomotive starting motor and increase the battery life of the starting technology needs to be solved urgently.

By adding an additional fast energy storage module in parallel to the starter battery of a generator or automobile and locomotive, by means of the fast energy storage module Power output assistance can effectively increase the starting current of generators or motor vehicles and reduce the output current of the starting battery. Therefore, this method can lower the cold starting current CCA specification or starting battery capacity of a lower performance starting battery, and can Provide the starting current required by the starting motor, and by replacing the starting battery with a lower performance, the internal resistance of the starting battery will generally increase. Therefore, with the help of the rapid energy storage module, the starting can be further reduced.

Take an automobile as an example. The load current of the existing automobile starter motor 31 is related to the automobile displacement CC. The displacement refers to the total volume of the air and gas mixture sucked by the internal combustion engine in a complete engine cycle. The cubic centimeter (CC) is expressed, and the size of the displacement is related to the vehicle's power, acceleration, fuel consumption and CO2 emissions; the cold start current amperage (CCA) is used to define the battery at 0°F (-17.8 °C) An indicator of the ability to start a car engine in a cold environment.

Withdrawing current, by replacing the starting battery 33 with lower performance through the present invention, the starting battery 33 with lower performance provides less drawing current of 203A (less than 40% of the 512A of the original starting battery) ), and by adding a fast energy storage module 13 in parallel with the lower performance starter battery 33 of the car and locomotive in the start mode, the auxiliary output of the fast energy storage module 13 provides the load current of the starter motor 31 It is 515A, so it can effectively increase the pumping current required by the starter motor and reduce the pumping current of the lower performance starter battery 33. Therefore, through this method, the device that is started by the starter motor, such as a generator or For automobiles and motorcycles, a starter battery 33 with a lower cold start current amperage (CCA) can be used to provide the load current required to start the motor 31.

The lower performance of the starter battery is a starter battery configured below the required performance value of the starter motor. The starter motor cannot be started separately, so that the fast energy storage module 13 and The starter battery 33 with lower performance jointly provides the power required by the starter motor 31 to achieve the purpose of starting, and then drives the engine to run. The fast energy storage module 13 is used to assist the power supply of the starter battery 33 with lower performance.

An embodiment of the present invention can determine whether the starter motor 31 enters the start mode by measuring a voltage of the lower performance starter battery 33 connected to the starter motor 31, because the starter motor 31 needs a battery during the start of the start. It is driven by instantaneous high current. At this time, only the starter motor 31 is connected to the starter battery 33 with lower performance. The starter motor 31 has only the lower performance starter battery 33. The current I _TH flows out at an instant, so the performance is lower. The voltage of the starter battery 33 will produce a sharply reduced waveform at the moment the starter motor 20 is started. After a predetermined voltage difference is generated, it immediately enters the start mode, and the predetermined voltage difference can be set Is the voltage of the starting battery 33 with lower performance when the starting motor 31 is stopped minus the first internal resistance value of the starting battery 33 with lower performance flowing through a current drawn from the starting battery 33 with lower performance The voltage of the starting battery 33.

At the same time, continue to refer to the embodiment shown in FIG. 1 and FIG. 2. In this embodiment, the fast energy storage module 13 is connected in parallel with the start battery 33 with a lower performance when the generator or steam locomotive is in the start mode. , In order to adjust an electrical output ratio of the lower performance start battery 33 and the fast energy storage module 13 to share the electric power to start the start motor 31, thereby extending the life of the lower performance start battery 33; for example, In the startup mode, the startup battery 33 with lower performance and the fast energy storage module 13 are connected in parallel to set the startup battery 33 and the fast energy storage module 13 with lower performance to provide the starter motor 31 respectively. The electrical output ratio of the load current I _L , in other words, the electrical output ratio of the starting battery 33 with lower performance is that the pumping current I _TH of the starting battery 33 with lower performance accounts for the starting motor The ratio of the load current I _L of the fast energy storage module 13 is the ratio of the electrical output of the fast energy storage module 13 to the load current I _C of the fast energy storage module 13 to the load current I _{L of the starter motor 31} The sum of the electrical output ratio of the starting battery 33 with lower performance plus the electrical output ratio of the fast energy storage module 13 is equal to 1, that is, the electrical output ratio of the fast energy storage module 13 is increased. The power output ratio reduces the electrical power output ratio of the starting battery 33 with lower performance, so as to achieve the purpose of prolonging the life of the starting battery 33 with lower performance.

Please continue to refer to FIG. 2, in an embodiment, for example, the low-performance starter battery 33 and the fast energy storage module 13 of a car, the fast energy storage module 13 is a super capacitor group, and the lower performance The starting battery 33 is a lead-acid battery. The lead-acid battery has a first internal resistance value and the supercapacitor group has a second internal resistance value. In the starting mode, the starting battery 33 and the quick storage battery with lower performance can be set. The module 13 respectively provides the electrical output ratio of the load current of the starter motor 31, which satisfies the following formula (1): R _r10 =I _TH / (I _TH ＋I _C ), R _r20 =I _C / (I _TH + I _C ), R _r10 is the electrical output ratio of the low performance start battery 33 of the fast energy storage module 13 connected in parallel to the lower performance start battery 33, and R _r20 is the fast energy storage module 13 is the electrical output ratio of the fast energy storage module 13 connected in parallel to the starter battery 33 of _{lower performance, I TH} is the pumping current of the starter battery 33 of lower performance, and I _C is the fast energy storage The pumping current of the module 13, the load current I _L of the starter motor 31 is I _TH ＋I _C , and R _C is the second internal resistance value of the fast energy storage module 13, which can be known from formula (1) By increasing the pumping current I _{C of} the fast energy storage module 13, and then reducing the pumping current I _TH of the starting battery 33 with lower performance, the purpose of reducing the output of the starting battery 33 with lower performance is achieved. It is possible to effectively extend the life of the starting battery 33 with lower performance.

Please continue to refer to FIG. 2, in an embodiment, for example, the low-performance starter battery 33 and the fast energy storage module 13 of a car, the fast energy storage module 13 is a super capacitor group, and the lower performance The starting battery 33 is a lead-acid battery. The lead-acid battery has a first internal resistance value and the supercapacitor group has a second internal resistance value. In the starting mode, the starting battery 33 and the quick storage battery with lower performance can be set. The energy module 13 respectively provides the electrical output ratio of the load current of the starter motor 31, which satisfies the following formula (2): R _r10 =1-(R _TH / (R _TH ＋R _C )), R _r20 =1 －(R _C / (R _TH ＋R _C )), where R _r10 is the electrical output ratio of the starting battery with lower performance, R _r20 is the electrical output ratio of the fast energy storage module, and R _TH is For the first internal resistance value of the starting battery with lower performance, R _C is the second internal resistance value of the fast energy storage module.

The embodiment of the present invention originates from the fact that lead-acid batteries will affect their life due to different pumping currents. Therefore, super capacitor packs are added. In this startup mode, the super capacitor packs are connected in parallel with lead-acid batteries with lower performance to share and provide Start the engine with electricity (for example, start the motor 31), and reduce the current drawn from the lead-acid battery with lower performance to extend the life of the lead-acid battery with lower performance. For example, set the electrical output ratio of the lead-acid battery with lower performance to About 50%, the electrical output ratio of the supercapacitor group is about 50%, which can reduce the current drawn by half of the lead-acid battery with lower performance, which can increase the use times of the lead-acid battery with the same lower performance by 2 Longer life is the first benefit; in addition, lower-performance lead-acid batteries deteriorate with the increase in the number of times of use, reducing half of the pumping current of lower-performance lead-acid batteries, making lower-performance lead-acid batteries The deterioration of the battery is slowed down by one-half, and the life span can be increased by more than 2 times, which is the second benefit; the lower performance lead-acid battery will deteriorate as the number of uses increases, resulting in the lower performance of the lead-acid battery The first internal resistance value gradually increases, while the second internal resistance value of the super capacitor bank is almost unchanged, and the electrical output ratio of the lower performance lead-acid battery is reduced until it reaches zero, which can greatly slow down The degradation degree of the lower performance lead-acid battery electrolyte reduces the degradation of the lower performance lead-acid battery by one-half, which can increase the life span by more than 2 times, which belongs to the third benefit; The power required to start the super capacitor bank of the starter motor 31 alone, even if the life capacity of the lower performance starter battery 33 is 1% or less (depending on the battery capacity), the super capacitor bank can be started as long as the super capacitor bank can be fully charged. Motor 31, compared with the normal lead-acid battery, when the original design ages to 50%, the lead-acid battery cannot draw the target current (such as cold start current amperage CCA), and now the lower performance starter battery 33 can be used sufficiently Charge the supercapacitor group to the lower limit of the real minimum remaining power of the startable voltage, so it can use up all the available power of the lead-acid battery with lower performance, and can achieve the purpose of extending the life of the lead-acid battery with lower performance. It is expected that the use times of lead-acid batteries with lower performance will be increased by 2 times, which is the fourth benefit; lead-acid batteries with such lower performance originally have an average life span of two years. Now the above-mentioned four multiplying benefits are combined. Low-performance lead-acid batteries can be extended to more than 16 times the life (lifespan is more than 32 years), but the life of the general car is about 20 years, so there is no need to replace the lower-performance lead-acid battery before the car is scrapped.

There is an idling stop system (start/stop system). When compared to a normal starter motor, the number of starts is N times. N is an arithmetic mean or a positive integer, where the electrical output ratio R _r10 of the starter battery 33 with a lower performance is set to 40% , Set the electrical output ratio R _r20 of the fast energy storage module 13 to 60%, and integrate the above four multiplying benefits ((100%/40%)×(100%/40%)×(100%/40) %)×2) divided by N, the lower performance of the starting battery 33 is increased by 31 times divided by the life of N or more, or the electrical output ratio R _r10 of the lower performance of the starting battery 33 is set to 30%, and the The electrical output ratio R _r20 of the fast energy storage module 13 is 70%, and the above four multiplying benefits are combined ((100%/30%)×(100%/30%)×(100%/30%)× 2) Divide by N, the lower performance of the starting battery 33 is increased by 74 times divided by N or more than the life span, or the electrical output ratio R _r10 of the lower performance of the starting battery 33 is set to 20%, and the fast energy storage is set The electrical output ratio R _r20 of module 13 is 80%, and the above-mentioned four multiplying benefits ((100%/20%)×(100%/20%)×(100%/20%)×2) are divided by Taking N, the lower performance of the starter battery 33 is increased by 250 times divided by N or more; the range of the electrical output ratio of the lower performance of the starter battery 33 is between 20% to 40%, and the fast The range of the electrical output ratio of the energy storage module 13 is between 60% and 80%, wherein the electrical output ratio of the starting battery 33 with lower performance plus the electrical output ratio of the fast energy storage module 13 The sum of the electrical output ratio is equal to 1. In this way, with the common output assistance of the fast energy storage module 13, the lower performance of the starter battery 33 can achieve the purpose of starting the starter motor 31, and at the same time, it can greatly slow down The degradation degree of the starting battery 33 (for example, a lead-acid battery) with a high performance achieves the purpose of prolonging the service life of the starting battery 33 with a lower performance.

When the processing circuit is in the starting mode, The switch is controlled so that the fast energy storage module 13 is connected in parallel to the start-up battery 33 with a lower performance; in a charging mode, the fast energy storage module 13 (such as a super capacitor bank) is used to have the lower performance The start-up battery 33 has a faster charging and discharging capability, and the switch is controlled to disconnect the fast energy storage module 13 from the parallel connection with the lower-performance start-up battery 33. The processing circuit includes a buck-boost module (Not shown), the low-voltage and low-performance starter battery 33 can be boosted to charge the fast energy storage module 13 through the buck-boost module (not shown), so as to charge the low-voltage and low-performance starter battery 33 The startup battery 33 boosts the fast energy storage module 13 until a preset condition is met, and the preset condition is that the lower performance of the startup battery and the fast energy storage module are assisted by the joint output to achieve The load current required by the starting motor 31 allows the fast energy storage module 13 to be connected in parallel at any time in the starting mode to assist the starting battery 33 to supply the load of the starting motor 31, but the charging mode of the present invention is not limited to this.
